With a quick carnal purr and a cackle that'll curdle the cream in your coffee, the titular character played by the late John Phillip Law (of Barbarella fame; a cinematic cousin also released in 1968 by the same producer, the zeitgeist-tapping Dino De Laurentiis) dives through gunfire and rainbow smoke into a physical camera rotation while the English version of the theme "Deep Down," as sung by Christy, enthralls.

What remains is 'gramophonic' spin art that only director Mario Bava would think to employ, putting terrific emphasis on a groove that doesn't let up.
